An object 6.0mm high is placed 18cm from a convex mirror of radius of curvature 18cm .
A) Determine the image distance using the mirror equation
1do+1di=1f. Follow the sign conventions.
B) Determine the image size using the equation for magnification m=hiho=?dido. Follow the sign conventions.
A certain part of an aircraft engine has a volume of 2.6 ft3. Determine how much weight is saved by using aluminum instead of nickel
Imagine a frictionless pulley (a solid cylinder) of unknown mass M and radius r = 0.200 m which is used to draw water from a well. A bucket of mass m = 1.50 kg is attached to a massless cord wrapped around pulley. The bucket starts from rest at th..
An airplane flies 200km due west from city Band then 285 km in direction of 28 degrees north of west from city B to city C. in a straight-line distance how far is city C from city A.
An object moving with uniform acceleration has a velocity of 14.0 cm/s in the positive x-direction when its x-coordinate is 3.18 cm. If its x-coordinate 2.95 s later is ?5.00 cm, what is its acceleration?
A 500g ball swings in a vertical circle at the end of a 1.5-m-long string. When the ball is at the bottom of the circle, the tension in the string is 12N
A spherical object with a radius of 40.0 cm has a net charge of 37.7uC distributed uniformly throughout its volume, Using Gauss's Law, calculate the electric field 71.5 cm from the center of the sphere
Three point charges are fixed to rectangular coordinate system, Calculate the magnitude and direction of the net electrostatic force on the charge on the x-axis
How much force is needed to hold a 7.0 cm diameter hose delivering 440 L/min through a 0.73cm diameter nozzle.
An airplane has a mass of 1.8×10^6 kg , and the air flows past the lower surface of the wings at 94 m/s .f the wings have a surface area of 1300 m^2, how fast should the air flow over the upper surface of the wing if the plane is to stay in the ai..
A 54.00 kg pole vaulter running at 10 m/s vaults over the bar. Her speed while she is above the bar is 1.0 m/s. Avoid air resistance, in addition to any energy absorbed by the pole, and determine her altitude as she crosses the bar.
Without taking the existence of the nebula into consideration, based on its apparent magnitude, how far away does the star in part (b) appear to be? What would the propotion error be in determining the distance if interstellar extinction were negl..
Many people mistakenly believe that the astronauts orbiting the earth are "above gravity." Compute the acceleration because of gravity, g, for space shuttle territory, 245 kilometres above the earth's surface (dashed line in sketch). Earth's mass ..
